RAIL DRILL.

Application filed March 29, 1920. Serial No. 369,453.

To (tZZ to hem it may concern I lie it known that we, l Vinrne T. iii-motion and Enrs'sr l Winner, citizens oi' the linited States, and residents of lla Grange and Chicago, respectively, in the county of Cook and titate of Illinois, have invented certain new and useful improvements in ltail Drills. olwhich the following is description, reference being had to the accompanying drawings, which form a part of our specification.

Our invention relates to aportable poweroperated drill for drilling rails after the latter have been laid or put into place; the

drill being intended to be secured to and adjrratably supported on a track car or truck provided. with suitable motive power and. arranged to move on the rails to be operated. on; our improved drill being especially intended for drilling holes in the base of the 20 rail for the insertion of anchor spikes or screw-spikes as the case may be.

One object of our invention is to provide a device more especially adapted for vertical drilling operations, but which inaj at the same time be adjusted at various inclinations orangles to a vertical plane so as to permit the device or drill to swing to opposite sides of a rail in order that drilling ofthe base on both sides of the rail may be readily accomplished. the operation of the drill-spindle being induced through suitable mechanism operated by the motive power of the track-car or truck, while the feeding of the drill-bit is preferably accom plished manually; the hand or manually operated feed-mechanism being of such nature that the drill will be held in its adjusted position, thus obviating the necessity for special'mechanism whereby the drillspindle will beheld in elevated position when the drill device is out of operation, while at the same time obviating the necessity for the exertion of great pressure by the operator during drilling operations. I

The objects and advantages of our invention will be readily comprehended from the detailed description ofthe drawings, wherein r t Figure l. is a plan view of our improved rail 1 drill shown applied. to a portion of track caror llIllClLw.

Figure is a detail sectional view taken on the line 553 of Figure 1 looking in the direction of the arrows.

Our invention contemplates a rail drill adapted to be secured to the platform or sills of a smalltrack car which travels along the rails to be operated on; one of the rails being shown A in Figures 1 and 2; while the track car is preferably provided with a pair of parallelly disposed side sills 10 arranged adjacent one side of the truck or t'a-ck car. The device comprises a bracket or frame 11 which is provided with an integral hub portion 12 adapted to receivethe spindle or shaft to which bevel gear 13 is secured; while gear 13 meshes with a. power-driven bevel pinion 1 1 which is adapted to be driven mounted clutch 16 is in operative relation with the extended hub 17. of the sprocket 15. The sprocket 15 is adapted to be driven in the particular exemplification disclosed, by means of a suitable sprocket chain 18 which is disposed about a drive sprocketsecured on the power shaft 19 ofan internal combnstion or other suitable motor indicated at 20.

The bracket or frame member 11 is provided with a number of parallelly disposed and spaced arms 21, 22 and 23, each of which terminates in a hub portion apertured to receive a shaft 241. The shaft 24: at a point intermediate of arms 22 and 23 is provided with a bevel pinion 25keyed thereto and arranged in mesh with the bevel gear 13, so that shaft 24 willbe rotated when power is transmitted to bevel pinion 14- through movement of clutch 16 into clutching relation with the clutching surface on hub 17 of sprocket 15. The shaft 24: at a point intermediate of arms 21 and 22 of bracket 11 is provided with a gear 26 secured to'the shaft so as to rotate therewith. The gear 26 1s arranged in mesh with a gear 27 secured to a sleeve 28 through which the drill-spindle .29 extends. The sleeve .28 is rotatably mounted at its endsin suitable bearings 30,

. 30 provided on a frame member or yoke 81,

of the shaft 24 therethrough; in other words,

shaft 24: also acts as a journal for the frame member 31 so as to permit'sidewise oscillation of the frame member 31. The upper end or arm of frame member 31 is intended to OiGlliiP the end of arm 21 of frame member 11 while the lower end or arm of frame member 31 overlaps the lower side of arm of frame member 11 and the ends of shaft 2 are provided with suitable collars 32, 1-32 whereby the shaft is held against longitiu ina-l movement and the frame members and various elements carried thereby maintained in operative relation with one another.

It is clearly evident from the construction shown and described that frame lTlQll'llOGl? 2-51,, with the elements carried thereby may be swung laterally so as to be disposed to either side of the vertical plane of frame niemliicr 11; that is frame member 31 with the mechanism carried therein may be swung to either side of the rail A which is being; operated on.

The sleeve 28 is rotat-ably' mounted in the arms of frame member 31; the sleeve on tending into the bearing' portions 39 of the frame" member Silas shown in Figure 3 and provided with suitable bushings as at 32 The sleeve 28 at its upper end is provided with a suitable collar 38 secured thereto and in abutting relation with the bearing portions 30 of the frame member 3-1, to prevent upward longitudinal movement of. the sleeve; while the lower end of the sleeve at a slight distance above the lower hearing portion 30 of framemeinber 31 is provided with a collar 341- secured thereto against movement lengthwise of the shaft but adapted to rotate At a point intermediate of coltherewith. lar 3d and the'bearing portion 30, sleeve 28 is provided with anti-friction thrust hearings 35 which'enable free rotation of tl e sleeve. The drill-spindle 29 is disposed through sleeve 28 and provided with slots orkey-wavs 36 extendinglengthwise of the drill-spindle, to receive suitable feathers 37 whereby the drill-spindle and sleeve. are rotatably secured together, while at the same time permitting the drill-spindle to move lengthwise of the sleeve. The drill-spindle 29 terminates at its lower end in a suitable drill-chucln asst 38, to receive the drillbit shown at 39, which may be held in the chuck in any suitable manner", as for example by a I setscrew 4:0.

The drill-spindle 29 at its upper end is providedwith suitable means for feeding; the drill-spindle into drilling position. I

In the particular exemplification, the upper end of drill-spindle 29 is provided with an elongated cylindrical head ll having pins or lugs 42 which extend into an annular groove formed in the spindle 29, see Figure 3, thus peri'n'ittinr; the spindle 29 to have rotation independently of head all. The

Lad-5 head 41 is extcrnall threaded. throughout a considerable portion 0!? its lemrih. frame portion Ell is providinl with a yoke l l extending above the fi" c portion and llu yoke is provided with an internally 'ilu'mdcd hub adapted to receive the externally threaded head slit which latter at upper end above the vol-2e ail s provided with suitable hand-wheel l4. il'ilh lhc constru tion just described, the operator may l'orw the (llllhfilllllhllt 2 downwardly iulo uponative or drilling position by turning handwheel let in proper direction so as :o :rcw the head -l-1 through the threaded hub in yoke 43, 'tluu eb v causingthe drill-sp nilio also to be forced downwmrdlv. ll, lralso wcitlent that the drill-spindle will be inuiutained in raised or any desired position b v turning the hundnvhecl and head in the proper direction.

The composite frame ll? 1. with the mechanisms carried thereby is supported through the medium of the hub portion ii f frame ll; the hub portion being adapted to receive an elongated sleeve 15 which. in turn, receives the spindle or shaft in to which bevel gear 113 is secured; the slccvu being of length to also extend through openings arranged in alignment at opposite ends of supportiiu frame member l7, see Figure 1. The frame member ell is shown rcctan. gular in formation to fit between the side sills 10. The frame member 47 may be more or less skeleton form with the sides i'lQLllQI Q/(l so as to overlap the side sills 1,0 to which the flanges are bolted or otherwise secured. The two end portions of the Frame member 45? are wovided with openingt's therethrough, to receive the sleeve 45; the openings and the sleeve 45 being provided with he va vs f the reception of suitable keys as shown at llti which will prevent rotution of sleeve 45 in support n5;- l'rumn member 47. The hub portion 12 of l'ramo 11 is also provided with a l ey-way or slot which The is adapted to receive a bearing-strip which has frictional relation with the sleeve 45; lhe. bearing-strip intended to receive the downward pressure exerted by the end of setscrew or bolt 49 which passes through a tapped opening" in a boss 50 formed on hub 12. It is apparent that when set-screw elf) is screwed downwardly a firm frictional relation between frame ill and the sleeve 45 will be provided, suflicicnt to hold frame 11 in any adjusted or oscillated position, due to the fact that the sleeve cannot rotate in the supporting casting or frame =17 because of the keys 48. The spindle 4.6 of gear 13 extends entirely through the sleeve and is provided at the outer end with a collar 51 so as to prevent longitudinal movement of the spindle; the hub of gear having abutting relation with the inner end o l sleeve 45 and the hub of frame 11.
